British rival Amir Khan has already expressed a willingness to face Brook, once he secures a world title, and the 147lb division also includes superstars Floyd Mayweather and Manny Pacquiao.

Asked what is at stake for him, Brook told ontheropesboxing.com: “Of course, of course it could be interesting and it is on my mind.

“I know that this is the key to Fort Knox. It’s a massive money fight out there, not just Amir Khan but international fights like Mayweather, Pacquiao. I think people in America and around the world will take note after beating Shawn Porter.”

Porter ripped the belt from Devon Alexander with a points win last December and his first defence ended in a chilling stoppage of the normally durable Paulie Malignaggi.
